Paramedics attempted to revive him and took him to a hospital, where he was pronounced dead shortly after 2 p.m., the sheriff's department said.

No foul play is suspected, the agency said in a written statement.

Hayes was a longtime songwriter and arranger for Stax Records in Memphis, playing in the studio's backup band and crafting tunes for artists such as Otis Redding and Sam and Dave in the 1960s.

Not a very nice man in his later years. He proves what religious bigotry was all about. He only left South Park when his own religion was insulted, even though they have insulted every other religion. That shows a poor person IMO. Regards his beliefs better than everybody else's.
